Abstract

The invention relates to an explosion-proof heater. The explosion-proof heater comprises a wiring base and a heating pipe body; and a wiring circuit is positioned in the wiring base. The explosion-proof heater further comprises an upper flange and a lower flange; the upper flange connects the wiring base with a control box of the explosion-proof heater; the lower flange connects the wiring base with the heating pipe body; the heating pipe body includes an air inlet near the lower end part of the heating pipe body, an air outlet near the upper end part of the heating pipe body, a heating pipe positioned in the heating pipe body, heating pipe fixed plates and a netty liner; the heating pipe fixed plates are flatly cylindrical, and are uniformly distributed in the axial direction of the heating pipe; two or more heating pipe fixed plates are provided; through holes are formed in the heating pipe fixed plates; the heating pipe penetrates through the through holes; the outer wall of the heating pipe is fixedly connected with the inner wall of the through holes; and the netty liner is uniformly distributed in the axial direction of the heating pipe. The explosion-proof heater is high in heating efficiency, and can guarantee the air flow moving speed in the heating pipe.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof electric appliances, and in particular relates to an explosion-proof heater. Background technique [0002] In industrial production, there are many occasions where hot air is required. Explosion-proof electric heaters are used to convert electrical energy into thermal energy to heat materials to be heated. During work, the low-temperature fluid medium enters the input port through the pipeline under pressure, and takes away the high-temperature heat energy generated by the electric heating element during the work along the specific heat exchange flow channel inside the electric heating vessel, using the path designed by the principle of fluid thermodynamics. The temperature of the heated medium is raised, and the outlet of the electric heater obtains the high-temperature medium required by the process. [0003] The electric heating tube of the existing structure has general heat dissipati...
